Oil pan leak
Hello all,
My n55 335i has a oil pan leak. I was able to get valve cover gaskets replaced under warranty at around 70k miles. My car now has 90k and I was told yesterday by bmw I had the leak. They said it wasn't too bad. I was just curious if anyone else that has had this let it go for some time without it getting too bad. I have a family mechanic that can easily fix for much cheaper then bmw but if it doesn't get too bad I was just going too not worry as I will Prob. Trade car in within 2 years. Just looking for for commendations

Depends on the leak. If it’s only covered with oil only around the studs and you are not loosing significant amount of oil u can delay the replacement of the gasket.

Yeah that's what I was thinking until it gets bad enough to do it

This is from Amazon reviews. Here's a couple of them. My 1989 BMW V12 was leaking oil furiously. It left puddles everywhere, and the entire underside was coated in oil, all the way to the back bumper. Changing the oil pan gasket is a huge job involving dropping the front suspension crossmember. So I tryed Liqui Moly after a fresh oil change, and after a few hundred miles my oil leaks slowed down 90%! I would never believe some snake oil in a shiny can would actually do as promised, but I am totally convinced! I will be changing the oil again and adding Liqui Moly every oil change This Stuff Works I own a 1991 BMW 535i with over 320,000 miles. I drive this car to work every day. I was adding half a quart of oil a month. I have not added any oil since. I had a 2009 BMW 335i which was leaking engine oil at a rate of about 1L per month; had to top off engine oil every once in a while. After using this, the slow leak stopped, and I haven't had a need to add engine oil since. Even after an oil change (which presumably flushed out most of this product), the leak did not come back.

BMW and oil leaks are synonymous. They are just not capable of making an oil tight seal.

oil leaks
I am curious about this moly additive and whether it works. If it helps the oil pan it will help valve cover and filter gaskets as well.
Thanks. |

Those oil additives/sealers do work depending on the condition of the rubber gaskets & seals. If they are terribly hard and brittle and now flat, they will not work. They work by softening and swelling the rubber.
I've heard good things about Bar's Leaks and Blue Devil. |

Ended up trading in this 335^ it still had oil pan leak and rear differential leak… idk if it was just me or what but that n55 was a constant leaking mess. I would never buy another n55 again lol.

Buying a bmw you can almost expect a valve cover, ofhg, oil pan leaking at some point around 100k or higher if your lucky. Most of us just expect that, pretty sure b58 are not gonna be any different. They're just newer so you don't see it as often

I am having oil pan leak on my N55. I wonder how did you deal with the leak in past 3 years?

I got rid of the car. I never fixed the pan leak. I just let it sit until I was told it was getting pretty bad and then dumped the car
